ORE-CONCENTRATOR.

SPECIFICATION forming part of Letters Patent No. 479,279, dated July 19, 1892.

Application filed September 30, 1891. Serial No. 407,859. (No model.)

To all whom it may concern.-

Be it known that I, GOTTLIEB D. HUSEMANN, residing at St. Louis, State of Missouri, have invented a new and useful Improvement in Ore-Concentrators, of which the following is a specification.

This invention relates particularly to an improved ore washer, separator, and concentrator, the object of my invention being to provide a device of this type that will subject the slime to the combined operations of washing, rilfiing, and concentrating, and one that will perform these functions with the least mechanism possible, thereby rendering the device cheap and simple, easy to operate, and thoroughly efficient.

WVith these objects in view my invention consists in the details of construction and the combination of the various parts, allof which will be fully described and claimed.

In the drawings forming a part of this specification, Figure 1 is a perspective view. Fig. 2 is a vertical longitudinal section. Fig. 3 is a cross-section on line 3 3 of Fig. 2, and Fig. 4 is a detail view.

In carrying out my invention I employ a frame or scafiold 10, within which my improved Washer, separator, or concentrator is suspended and adapted to be rocked or swung horizontally from side to side. This washer, separator, or concentrator is composed of an upper box 11 and a lower box 12, said lower box being hinged to'the lower end of the upper box and maintained in the proper position by means of a ball or strap 12, which is connected with the upper box and passes beneath the lower box, said bail or strap being provided with a series of perforations 12 by means of which and the pins 12 the lower box can be adjusted at various angles to the upper box.

The upper box, and consequently the entire machine, is suspended from the top beams of the frame by means of the suspending straps or links 11, said straps or links having loops upon their lower ends, which engage hooks attached to the sides of the upper box, and the relative lengths of the straps or links are such that the upper boxis suspended in an inclined position and the lower end of said. box is left open and provided with aspout 11",

the purpose of which will appear farther on. The upper straps or links are provided with a series of apertures to permit adjustment of the box. The upper and lower boxes are constructed with solid bottoms, and along the longitudinal center of each bottom is arranged a tube-conduit 11 and 12, respectively, said tubes or conduits extending from end to end of each box, and at their respective lower ends are provided with the discharge-pipes 11 and 12 the pipe 11 discharging into the upper end of the lower box and the pipe 12 discharging into any suitable receptacle arranged beneath the'lower end of the lower box. Each of the discharge-pipes is preferably provided with a stop-cock, whereby the discharge can be regulated when so desired.

A short distance above the bottom of the upper and lowerboxes are arranged the plates or diaphragms l1 and 12 respectively, the said plates or diaphragms sloping gradually from the sides of their respective boxes to the longitudinal centerof the same, the lower portion of each plate or diaphragm resting upon the top of the tube or conduit beneath the same, and the plate and tube are perforated along the line of contact, as at 11 and 12, whereby an escape is had from the upper faces of the plates into the tubes or conduits beneath the same. The plates or diaphragms are also provided with a series of rifliles 11 and 12 respectively, said riffles extending from side to side of their respective boxes, and the bottom of each riffle is provided with a series of small perforations 11 and 12", respectively, whereby water passing between the bottoms and plates may ascend into the riftle, thereby washing theore contained therein and assisting in the separating or concentrating operations. ater is introduced into the boxes between the plates and bottoms thereof, at the upper ends of the same, the pipe 11 being connected with the upper box, while a pipe 12 leads into the lower box, the pipe 12 being connected with the pipe 11 by means of a coupling 12, and this coupling is also provided with a stop-cock. Each box is provided with discharge-outlets at the lower end of the same, as clearly shown, said outlets being closed while the machine is in operation, but are opened when it is desired to clean the same. A sieve 13 is arranged at the upper end of the upper box and adapted to receive the crushed ores to be washed or concentrated, said sieve being constructed in the form of a hopper, and it is supported between the plate or diaphragm 11 and a crosspiece 13, said plate and cross-piece forming a seat to receive the sieve, but providing an opening 13 for the escape of slime after it has become thoroughly saturated, and in order to prevent its premature escape I provide a cloth or apron 14, which is attached to the sieve and rests beneath the same.

A hood or cover 15 is constructed and arranged to cover the large perforations in each riffle in order to prevent any precipitate but the metal escaping into the tubes or conduits, and these hoods or covers are preferably united by a series of yokes or connectingplates 15, which when forced down upon the riffle-partition straddle the same and serve to hold the hoods or covers in place without any further means of attachment.

In order to rock or swing the boxes from side to side, I provide a crank-shaft 16, which is journaled to the side of the frame, and connecting said shaft and the upper box are the pitmen 16, one near each end of the box, whereby when the crankshaft is revolved by means of the handle. the pitmen will be reciprocated, likewise the u pper box, and as the lower box is connected with the upper box both by hinges and the bail said lower box will be moved in unison with the upper box.

In operation the crushed ore is reduced to slime and deposited in the sieve, which prevents large pieces being deposited upon the riflle-plate. The boxes are now reciprocated, and the cloth prevents the slime passing to the riftles until it becomes thoroughly saturated, whereby the metal will quickly settle to the bottom, and by this means a surface flow is prevented and I am enabled to save a greater portion, if not all, the float metal which would be otherwise carried off. The upper box being inclined,the ore will descend from one riffle to the other, and the water ascending through the bottoms of said rifiles will thoroughly cleanse the ore therein and serve to separate and concentrate the same. The metal, being heavier, will settle on the bottom, and the reciprocation of the box will have a tendency to concentrate at the longi tudinal center, where it will escape into the tube or conduit and by that means be led to the lower box, when it is subjected to a second cleaning. The water carrying the dirt will escape at the lower end of each box, the upper box being provided with a spout to prevent the water entering the lower box. The force of the water can be regulated as desired by means of the stop-cocks. The metal after being led to the lower box is operated upon in the same manner as in the upper box; but it will be noticed that the riffles are shallower and also that the hoods may be dispensed with. The metal is led off by the tube or conduit and caught in any suitable receptacle arranged beneath the lower end of the lower box, and by means of this improved apparatus and method of operation I am enabled to wash out or separate and concentrate a very large percentage of the metal, very little, if any, escaping. as float metal.

The lower box canbe readily regulated by means of the pins and perforated bail, and the inclination of the upper box can be varied by means of the perforated upper strap or links.

Having thus described my invention, what I claim, and desire to secure by Letters Patcut, is

1. The combination, with the frame, of the upper boxadjustably and pivotally suspended therefrom, the lower box hinged to the upper box and adj nstably suspended therefrom, the horizontal crank-shaft journaled to the side of the frame, and the pitmen connecting said shaft and the upper box, whereby as said shaft is revolved the boxes will be reciprocated horizontally, substantially as and for the purposes described.
